PP actually refers to polypropylene, which is mainly used in indoor cold and hot water supply systems in buildings and industrial anti-corrosion ventilation systems. Compared with pipes of other materials, it has good advantages:

1. No corrosion: PP pipe valves can withstand the corrosion of PH value in a wide temperature range, ranging from 1 to 14 in high concentration of acid and alkali.

2. Wear resistance and no scaling: The inner wall of PP pipe valves and fittings is uniform and smooth, with small flow resistance and no scaling.

3. Reduce vibration and noise: PP pipe valve has excellent sound insulation performance, which can significantly reduce vibration and noise caused by liquid flow.

4. Anti-freeze cracking: PP material has excellent elasticity, so that the section of the pipe and pipe fittings can expand together with the frost heaving liquid without bursting. 5. Anti-condensation, less heat loss: PP material is a poor thermal conductor, which can reduce condensation and reduce heat loss.

6. Simple installation: PP pipe valve is light in weight, easy to install and operate, and has weldability.
